BART is a great transit resource. People who live within a ten minute walk of BART are going to be very, very happy about this in the coming decade.

Buses stuffed to overflowing are terrible (and even dangerous) for shoppers.

The 2.2 very flat miles between the MacArthur BART station and the Emeryville Ikea/Bay Street stores is an excellent candidate for bikeshare (assuming excellent bicycle infrastructure was also put in for those 2.2 miles.)
